Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
dong nan » dong yang, dong sin, dong bin
hua gene » human gene, a gene, hy5 gene
part mun » part mind, part ten
kong siu » kong eiu, dong sin, kong sar
wong siu » wong shiu, wong sau, wong siew
hua ren » hua chen

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong nan) OR (yang yang)) yala ((hua gene) OR (hua ren)) part mun ((kong siu) OR (wong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong nan) or (yang yang)) yala ((hua gene) or (hua ren)) part mun ((kong siu) OR (wong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong nan) or (yang yang)) yala ((hua gene) or (hua ren)) part mun ((kong siu) OR (wong siu)) ;*.
